CallerIDDetectMethod Settings

[bsdaiwa]

Would anyone know what the correct setting for Physical Interfaces>Line>Port Setting >CallerIDDetectMethod would be for Argentina? Here are the OBi selections but I don't know which one is the correct one.
FSK(Bell 202)
FSK(V.23)
DTMF(Finland,Sweden)
DTMF(Denmark)
The phone I am using is a USA version so the Phone setting is correct its the line setting that I am not sure of.
I found this website http://www.carrollcommunications.com/locales/argentina.html but it says FSKD and that is not listed in the OBi selections.
Thanks

Try FSK(V.23).  That is the ETSI standard.
